Discovering noises from your car frequently is never comforting, so listening noises on your Renault Twingo suspensions when you go over a speed bump can be worrying. This sign may be a sign of a minor issue as well as a warning of a much larger repair to come. In any case, it is necessary to check the cause and take the necessary actions to eliminate the issue, it is with this goal in mind that we wanted to write this article to support you see more clearly. We will first see the possible explanations for a crack when the speed bump passes, then, what can be the reason of a squeaking noise when a speed bump is being passed and finally what to do if you have another noise when a speed bump is passed.
Suspension cracking noise Renault Twingo
Check Renault Twingo suspension
If you notice a suspension noise when you pass a speed bump on your Renault Twingo, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. In fact, it may be the suspension cups, which, when they are old, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To verify if this is the issue that worries you, take a dented road and listen to the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of swapping them as soon as possible or you may damage other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have researched for “Renault Twingo suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. In fact, when the cardan bellows get out of date and the dirt/dust accumulates inside them their operation is degraded and it is possible to experience a noise when they are in torsion. To verify this, you can try both types of torsion, first vertical with suspension compressions on the speed bump passages, and horizontal when you are going to turn at low speed. If it cracks in these two situations you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Renault Twingo, don’t hesitate to visit this content.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Renault Twingo passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you adjust direction. If this is the situation, the parts that may have been damaged by normal wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to verify it, place it under the vehicle and apply twists on each of its elements to verify that there is no special play on one of them, they are expected to endure you quite strongly over their entire travel. Please remember to take your vehicle to your auto mechanic or replace them if they are involved.
squeaky noise speed bump Renault Twingo
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you go over a speed bump with your Renault Twingo, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can provoke this squeaking noise. Bear in mind to verify by passing under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case take them off from the cradle and grease them, this should solve the issue.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, in fact, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the car, a noticable fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise happens when you pass a speed bumps or any holes with your Renault Twingo. To swap them go to your mechanic.
Other speed bump noise Renault Twingo
If, even though all its assumptions, you still can’t uncover the origin of the noise your Renault Twingo makes when you pass a speed bump, we advise you to refer to this content on a loud noise on Renault Twingo or to visit your auto mechanic in order to carry an in-depth check on your Renault Twingo and determine this issue.
